You may try this logic. Same is used in imgui_demo.cpp


void test::OnUIRender(bool *p_open)
{
    if (!ImGui::Begin("test_test", p_open))
    {
        ImGui::End();
        return;
    }

    // ... window contents here
    ImGui::Button("Button");

    ImGui::End();
}

in your draw loop


    bool show_Win = true;

    while (render) {

        // ...

        ImGui::NewFrame();
        //  ...

        if(showWin) OnUIRender(&showWin);
            
        // ...
    }

If window closed, ImGui will set showWin false, save it outside loop and use it to show/hide window in next frame. manually set it to true if you want to show window again
